Clip 10 of the present invention forms following structure: fastening sheet 22 is roughly along the extending circumferentially of leaf spring main body 12, and its front end 25 is towards the radial direction inside bend of leaf spring main body 12.Therefore; Shown in the double dot dash line of Fig. 6, even instrument T catches first front end 25 of grabbing by sheet 20 and fastening sheet 22, the front end of instrument T is grabbed by sheet 30 towards second with the mode on the front end 25 that can not be stuck in fastening sheet 22 and is moved; Therefore; Shown in the solid line of Fig. 6, can catch first to grab by sheet 20 and second and grab reliably, thereby can engage the releasing operation swimmingly by sheet 30.
Yet; The fastening sheet 22 that is formed on this clip 10 is not the assigned position of grabbing by sheet 20 from first; Towards the outer circumferential face of leaf spring main body 12 and the structure of extending to oblique below; But have as stated roughly along the part of the extending circumferentially of leaf spring main body 12, and front end 25 is towards the radial direction inside bend of leaf spring main body 12.
Like this, because the fastening sheet 22 of this clip 10 has along the part of the extending circumferentially of leaf spring main body 12, therefore, the back side that fastening sheet 22 is grabbed by sheet 30 with the angle and second that approaches the right angle engages (with reference to Fig. 6).Consequently, the back side sloped contact that the 27a of fastening portion and second is grabbed by sheet 30 prevents to slide diametrically, thereby the groove 32 that the 27a of fastening portion and second is grabbed by sheet 30 tightly engages, and can leaf spring main body 12 be maintained the state of enlarged-diameter.
In addition, the outer surface of the front end 25 of crooked fastening sheet 22 becomes mild circular-arc curved surface (with reference to Fig. 6) in the radial direction of leaf spring main body 12.Therefore, as stated, the front end of the instrument T that can will move towards the outer surface side of fastening sheet 22 with the mode of the front end 25 that can not be stuck in fastening sheet 22 guides to second swimmingly and grabs by sheet 30.
In addition; As shown in Figure 6; In this mode of execution; The 25a of portion foremost of fastening sheet 22 is towards first slit 16 bendings of grabbing by place, the end of sheet 20 sides that are positioned at of leaf spring main body 12, and the outer circumferential face that is formed on the leaf spring main body 12 that is positioned at than surrounds this slit 16 thus is the inboard of the radial direction of backup plate spring main body 12 more.Therefore, as stated, when with instrument T with first grab by sheet 20 and second grab by sheet 30 catch and make its near the time, can make instrument T be difficult for being blocked, thereby can further catch first to grab by sheet 20 and second and grab reliably by sheet 30 by the front end 25 of fastening sheet 22.
In addition, as stated, after catching two to grab tightly by sheet 20,30, if make they further near the time, then can make the 27a of fastening portion of fastening sheet 22 break away from groove 32, grab engaging thereby remove fastening sheet 22 with second by sheet 30.In addition; When make first grab by sheet 20 and second grab by sheet 30 near the time; Second grabs by sheet 30 and can and on width direction, move so that second grab by sheet 30 away from fastening sheet 22 with the tapering 23c sliding contact of base portion 23 sides of fastening sheet 22, thus as shown in Figure 2 can make second grab by sheet 30 move to reliably with the first fastening sheet 22 hands-off positions of grabbing by sheet 20 on.
When under above-mentioned state at leisure back off tool T make first grab by sheet 20 and second grab by sheet 30 open and away from the time; Under the effect of the elastic recovering force of leaf spring main body 12, make and insert sheet 29 and in slit 16, slide; And make leaf spring main body 12 reduced; Therefore, can flexible pipe H be fixedly clamped in pipe arrangement P.
At this moment; Because grabbing by sheet 20 from outstanding towards the outside of the radial direction of leaf spring main body 12 first, extends the fastening sheet 22 of being located at this clip 10; Therefore; The interior week that makes leaf spring main body 12 with closely the contacting in full week of the flexible pipe H that will clamp, thereby can flexible pipe H be clamped on the pipe arrangement P, and can improve sealing of the flexible pipe H that is connected with pipe arrangement P etc.
In addition; In this embodiment; Because the 25a of portion foremost of fastening sheet 22 makes narrowed width because of the lateral margin 25b that has excised the 27a of fastening portion side, therefore, form width than the lateral margin 27b of the width direction central side that has excised leaf spring main body 12 and to be provided with the width of part of the 27a of fastening portion narrower.Therefore, as stated, when the diameter of leaf spring main body 12 when the state that enlarges begins to dwindle, can prevent the 25a of portion foremost of fastening sheet 22 and second situation of grabbing of slit 16 in, sliding, thereby the diameter of leaf spring main body 12 is dwindled swimmingly by sheet 30 interference.
